Fig. 6

Side views of a LuAG:Ce rod with a glass (n = 1.52) concentrator with optimized Bézier shape attached to it with simulated angular distributions of light at different stages. The numbers in the angular distributions show the fractions of light at the different stages. At the bottom the Bézier shapes of the two sides are shown (solid lines) together with the CPC shapes (dotted) of Fig. 5
